Important: Follow all wizard instructions: If a mistake is made during commissioning or the wizard
encounters an error, commissioning must start over.
Commissioning may take several minutes to complete. This process is complex due to several
factors:

Important: After configuring and commissioning is successful, make a backup of the system from
the LCD via the Shortcuts > Backup menu. This allows the system configuration to be restored
in the event of a controller replacement.
